Abstract
A relatively power efficient, low flow-rate pump comprises an integral rotor-impeller on a hollow shaft which forms the rotational axis. The rotor-impeller is a permanently magnetized with alternating poles about its periphery faces and at least two channels extend through the rotor-impeller from the interior of the hollow shaft to the periphery of the rotor-impeller. The diameter of the rotor-impeller is in the range of from about 5 mm to about 30 mm and the operating rotational speed of the rotor-impeller is from about 10,000 RPM to about 50,000 RPM.
